Abstract:

This project presents the design and implementation of Modular Multilevel Inverter (MMI) to control the speed of Induction Motor (IM) drive using marine water pumping applications. The proposed inverter is of fifteen levels and controls the speed of an IM drive which is fed from solar photo voltaics. It is estimated that the energy consumed by pumping schemes in an on-board ship is nearly 50% of the total energy. Considering this fact, this paper investigates and von-board the proposed control design with reduced complexity intended for marine water pumping system employing an induction motor (IM) drive and MMI. Performance of inverter can be improved by the help of Proportional-Integral (PI) and Fuzzy Logic (FL) based controllers . A comparative analysis has been made with respect to the terms of peak overshoot, settling time of the controller and Total Harmonic Distortion (THD) of the inverter. The performance of the proposed controller is evaluated and compared to a conventional PI controller for various operating conditions. Results show that the proposed fuzzy logic controller significantly improves the system performance, resulting in higher efficiency, lower harmonic distortion, and faster response in comparison to the conventional PI controller.

Keywords: Proportional Integral, Fuzzy Logic, Total Harmonic Distortion, Peak overshoot, Settling time, Speed Control, Power Quality
